Take it for what it's worth...
I personally saw one of the axes (one of five) sell for 300 mil within a week of its existance.
The orc helms have never been available, so no telling on prices on those, although i would guess 200 each as a low end.
The high bid on the bracelet was 160 mil and it was then no longer available for bidding, as it had been sold to a "guild" member of the seller - you I suppose.
The scroll (one of three) - Yible, i am glad you sold yours, as it would have otherwise been rolled into the seemingly endless list of event items that you have had stolen from you.
